One viewer. Every drawing. Inside your product.

iframe + PostMessage

Drop the viewer into any frontend — React, Vue, Angular, .NET, SAP. No npm package, no framework lock-in.

Every format in one viewer

PDF, DWG, DGN, IFC, images, MS Office and 100+ more. One engine, one integration.

Self-hosted

Runs on your Windows Server. Drawings never leave your infrastructure.

You own the UI

Your app decides which tools are visible, who can use them, and where the results go.
